To (all whom it may concern:

Be it known that we, ORLA II. WATKINS and CHARLES F. SKELLENGER,citizens of the United States, residing at Clinton, in the county ofClinton and State of Iowa, have invented new and useful Improvements inWire-Working Machines, of which the following is a specification.

This invention relates to a wire-working machine. The machine may beeffectively employed for various purposes, although in practice it hasbeen found highl advantageous in the formation of wire ro s of a kindpeculiarly adapted-to a s ring structure emippyed in the makeup 0various articles of niture.

In the drawings accompanying and forming a art'of ths specification werepresent one e ective organization embodying our invention and which wewill set forth in full in the following description. The machine thusrepresented is arranged to form with accuracy and rapidity crimps orcompound bends in a wire blank or rod at preselected distances and alsoto form on the ends of said blank hooks or bends, so that the finishedproduct can be readily connected to other wires of a sprin structure.

Re erring to the drawings, Figure 1 is a front elevation of awire-working machine embodying our invention and showing an intermediateportion thereof removed. Fig. 2 isa detail view in elevation ofwire-feeding rolls and certain poWer-transmittinggears. Fig. 3 is aperspective view of a shaft and certain cams and other devices carriedthereby.

Fi 16 is asimilar view of the upper and lower ics shown as separated. Fig. 17 is asimilar view of the article made by the machine constructed ashereinafter described.

Like characters designate like parts in all the views.

The framing for supporting the different parts of the machine may be ofany suitable character, being represented as involving in itsconstruction a bed 2 of any desirable size or material, from the headand tail ends of which the legs, each denoted by 3, depend. Upon theopposite ends of the bed the standards or. uprzghts 4 rise andconstitute a partial support for the shaft 5, disposed longitudinally ofthe machine.

In the machine shown in the drawin s we feed thereinto from asuitably-mounted reel (not illustrated) wire and intermittently severthe wire into a predetermined length to constitute a blank. After theproduction of the blank we form in the same, and in the present instancein succession, a series of crimps and also shape the ends of the blankto present hooks. Each crimp is in the nature of a compound bendconsisting of two deflected ortions and an intermediate oppositely-deected portion, the several crimps being created by successively andindependently operative die mechanisms hereinafter more particularlydescribed. Before the wire is cut it is fed through a suitablestraightening device, the one represented being denoted in a general weand being of a familiar type a detai ed description of the same isunnecessary. After the wire leaves the straightening device it is passedbetween the superposed feed-rolls, each designated by 7, whichpositively ad- -vance the leading or free portion of the wire toward thecutting, crimping, and bending mechanisms. One of the rolls shown in thepresent case is represented as connected by a gearing (designated in aeneral way by 8) with a driver, as 9. The river is illustrated asconsisting of a pulley running loose on the shaft 5 and adapted to be 0eratively connected at regular intervals wit said shaft and in such away as to impart to the latter one full turn.

Rigidly united with the shaft 5 in any de "?5. sirable manner is what isknown in a number result in the rotation of the shaft.

said rod being connected at a point beyond the lever in a mannerhereinafter described. By drawing the rod 14 to the right the effectiveportion of the latch 12'will be lifted in i 5 order to permit thespring-actuated bolt 11 to be instantly thrust orshot out by the forceof its s ring into operative engagement with the pn ey 9 in order tooperatively connect said pulley with the shaft 5 and naturally to 0forth in-a contemporaneously-pending apli o.

the the movement. of the wire; but as rther description will hereinafterafter it leaves the straightening device 6 passes in contact with the.up er The wire ignated by 15. There are several of .these fixed .orlower die members 15 represented in Fig, 1, illustrative of theorganized machine.

- They are also clearly represented in Figs. 8 to The respective diemembers 15 are rigidly carried by the bases 16 of. standards 17,disposed vertically above the bed 2 of the machine. The standards17,which, asvwill be hereinafter apparent, carry the upper die memberscooperative with the die members 15, res ectively, are adjustablelongitudinally o the machine in order to effect variations in distancebetween the crimps, and for I urpose the bases 16 may bemounted for .siding movement along the upper side of the bed 2. The'bases arerepresented (see,- particularly Fig. 4, for example) as havin screws18on their under sides, the shanks; o 3 6c the screws thecross-barslQ, theopposite ends of which" passing through perforations in are adapted-..to engage suitablypositioned flanges, as 20, within the ,hollow orcham-' bered .bed 2.

held inits working or horizontal .a leaf-spring, as 30'. The rear en ofthe'bo desired relations can be thus maintained bythe action of thescrews.

Each of the lower or fixed die members 15 is rigidly united to astandard 17 and rests on a base 16 of the cooperating standard.

The upper die members are each designated by 21 and are adjustablyunited in some convenient Wag; with the lower ends of the slides 22 onthe The slides 22 arev carried for vertical reciprocation in suitableways on the standards 17 and are normally held elevated by coiled pullsrings, as 23, slides and standards. When the. sli es'are elevated, theirupper ends or antifrictionrolls,'as 24, thereon engage the ineffectiveportions of the peripheries of came, as 25, splined to the shaft 5,which, it will be remembered, is given intermittently afull-or completerotation. It naturally follows that each cam takes the same motion, therotation of a cam the effective portion thereof presses a slide 22downward, so that the die member-21, carried by said slide, can

006 'erate with a cooperating die member 15 to orm a crimp in the wire.-portions of the cams 25 are so related that the cams operate in seuence, and when the wire or blank is under t e action of the diemechanisms it is drawn 0 positely, the a blank being cut from the lea'ng portion ofthewire,

as, reviously stated herein.

' he die mechanisms, to which reference has been made in a general way,will be;.de-- scribed more in detail.

-puliey- 9 to operativelysiaee'ti tial operation of the machine afterthe shaft starts to rotate is the severance of the forward end of thewire to form a blank, and the means shown for accomplishing this resultinvolves a cutter, (designated in a general way b 32 and represented indetail in Fig. 6 and a so shown in a number of the other figures forexample, Figs. 8 to 12, inclusive.)

The forwardortion of the stock during the formation the crimps thereinis maintained in the notch 27 by a detent, as 33, of

angular form, thelonger arm of which is sup ported for rocking) movementby suitab earings upon the lock 28. The lower arm of the detent 33 has anotch which registers with that in the block 28 to form a uide-passagefor the extreme advance end 0 the wire. The detent 33, wlich is of thegravity type, is normally maintaired against movement 'y a gravit-latch, as 34, ivoted at one end to one of t e bearin s which carriesthe detent 33 and shoulderer? between its ends'to en age the detentbelow the center of motion 0 the latter. The latch 34, as willhereinafter appear, is elevated in order to free the detent and effectthe ejectment from the crimpin mechanism of the crimped and iriisheproduct.

As previously stated, the cutting mechanism involves a cuttin member, as32, the same being substantia y of cylindrical form and bei n gsupported for turning and endwise movement by a boxing, as 35, supportedon the framework of the machine. On the extreme forward end of thecutting member 32 is a segment 36, having one of its edges sharpened toproduce a cutting edge, the sharpened portion being at the left in Fig.8. The segment, the outer surface of which is concentr1c with theforward reduced portion of the c lindrical cutting member 32, 1s given apartral rotation forward and then backward, being adapted on its forwardmovement to cut through or snip off a predetermined length of wire. Thesaid forward end of said cutting member turns in a transverse bore inthe block 37, which transverse bore opens into a longitudinal borethrough which the wire is fed, the place at which the two bores intersect being so shaped as to produce an edge which cooperates with that ofthe cutting member 32 in severing the desired length of wire. In Fig. 8the segment is illustrated as being above the wire, the latter beingshown 55.

by the arrow in the same figure as moving toward the right in saidfigure.

Extendin longitudinally through the cut ting member 32 is a pin orelongated spindle 38, which extends beyond the opposite ends of saidcutting member. Onl a short len th of the pin or spindle extends eyondthe orward end of the cutting member, so as to present a projectionaround which the cut end of the wire is adapted to be bent by the actionof the segment 36.

The part 32 in addition to serving as a cutting member also serves, withthe pin or spin dle, as a hook-forming means.

I The block 28 is rovided with a cylindrical member 39, a dup icate inconstruction of the part 32, except that the bending-segment 40 of saidcylindrical art 39 has no cutting edge. The bending mem er 39 hasassociated therewith a pin or spi'idle 41, constructed andoperating-exactly like the pin 38. The segments 36 and 40 bend the freeends of the wire-blank around the respective concentric pins 38 and 41after the said wire has been cut by the action of the cutting portion ofthe segment 36. After the shaft 1s thrown into action the first thiargthat takes place is, as previouslv set forth, the severance of theadvance end of the wire, and this is accomplished by the cutting edge ofthe segment 36.

ing the effective part of said cam 42 and serving through certainintermediate devicesto b. ing about a back-and-forth motion ofthecutting member 32. A lever 43 is fulcrumed between its ends on thestandard 44, rising fr om the up er side of the bed 2, the upper end ofthe ever having a projection situated in the groove of the cam 42 andno:- mally located at the apex of the V portion thereof. The lower endofsaid lever is connected by a link 45 with the rack-bar 46, ex-

tending through a longitudinal opening in the boxing 35, and the teethof which are adapted to mesh with a pinion 47, feathered on, the cuttingmember 32. The canr 4 2 when it rotates under the action of, the shaft 5causes the projection on the u )pereint of the rocking lever 43 to rideout of the V portion of the peri heral slot and into the straightportion thereo and during this motion the segment 36 through theintermediate parts moves f.om the position shown in Fig. 8 to thatindicated in Fig. 9, in which position it remains until the cam has madepractically a complete rotation or until said p. ejection enters theother branch of the said V por tion, at which time the lever is returnedby the cam to its primary position, a reverse motion being naturallyapplied to the cutting member 32.

It will be assumed that the shaft 5 has been started, as hereinbeforedescribed, and that the cam 42 has commenced to rotate.

When

it rotates, it will be understood that the rocking lever 43 is operatedin such manner as to draw the rack-bar 46 toward the left in Fig. 6 andto rotate the pinion 47, and hence the cutting member 32, to cause thesegment to travel f om the position shown in Fig. 8 to that representedby Fig. .9, as before described. On the opposite motion of the lever thecutting member th: ough the intermediate pa; ts will be ietu; ned to its0;.iginal position, or that shown in Fig. 8, for exam le. When thesegment 36 nioves from t ie position shown in Fig. 8 to that representedin Fig. 9,.

it list of all cuts through the wi'.e, subsequent to which its flatinner face 0'. the effective bending portion thereof cm ls the cut endof the blank around the pin 38. While the part 32 is being given itsadvance partial 1otation the same motion is taking place with respect tothe part 39, so that the segment 40, which rotates oppositely to thesegment 36, can by its fiat face bend the right free end of the blank a1ound the pin 41.

It is necessary by the organization desc: ibcd to stop the feed of thewire during the cutting, crimping, and ejecting operations, and thisresult we secure by imparting an endwise movement to the cutting member32 in order to biing the body thereof in such position as to close theoutlet of the longitudinal bore of the block 37. Upon the said cutting1118111- ber 32 at a suitable place is a stud 48, shown as anantifriction-roll, adapted to cooper ate with the beveled face of a cammember 49, suitably rigidly attached to the forwai d side of the boxing35. When the pat t 32 was rotated to b; ing about the sever ance of thewire and the bending of the cut end about a in, the stud, rojection, orantifriction-rol 48 was cause to ride against the beveled face of thecam 49, so as to impart an advance movement to said part 32 and to bringits impe; forate portion opposite or into coincidence with the outlet ofthe longitudinal bore of the block 37 and so that the advance end of themajor po;tion of the wire will st. ike against the said imperforate portion to an est the further feed of the wire. The fo; ward n" otion ofthe cutting member 32 is in opposition to the coiled pi ot1 actile orpush spi in 50, smrounding the rear por tion of said cutting member andbearing against the boxing 35 and also against a suitable stop onsaid-cutting merr bez'. On the fo; ward moverr. ent'of the cuttingmember to effect the 9.1 rest in feed of the wire the sp1ing 50 is conpassed, whereby on the return otative 1r. ovement of said cutting memberthe latter may be retracted by the ex anc'ing-sp1ing, the operationbeing conclu ed when the roll 48 asses out of contact with the operative'sufgce of the cam 49.

As the wire when crimped is drawn toward the intermediate portion fromits opposite or hooked ends, it is essential that the pinsrior to thecrim ing 0 eration should be eed from the said 1100 ed ends. This resuit is accomplished by the rearward endwise movement of the pins. Wewill describe, of course, only one of the pins and its operating and adjunctive devices, as the same description applies to the other parts. Therear end of the in 38 (see'Fig. 6) extends through a suitab e guideerforation in a lateral extension on the bracllzet 51, the rear portionof the-pin being encircled by a coiled push-spring, as 52, engaging oneof the checknuts, between which one arm of the suitabl mountedelbow-lever 53 is mounted, said arm having a perforation to receive thepin or rod 38. The spring 52, it will therefore be apparent, by engagingone of the check-nuts presses the pin 38 normally forward, so as tomaintain the extreme front end in osition to receive the wire to be bentabout t e same by the segment 36. The free arm of the elbow-lever 53fits in an aperture 54 in the under side of an actuator 55, adjustablyconnected at one end with the rack-bar 46, from which it will beapparent that said actuator or bar 55 partakes of the movement of therack-bar. The formation of the aperture 54 produces two shoulders on theunder side of the actuator 55, between which the free arm of theangle-lever 53 is normally disposed. The shoulder on the rightin Fig. 7is n01 mally out of contact with said free arm. 7 When the rack-bar 46is moved toward the left in Fig. 6 to effect the rotation of the member32 in the manner hereinbefore described, the actuator or bar 55 is movedin a corresponding direction, and just after the hook is formed in theleft end of the wire the shoulder on the right on the under side of saidactuator strikes the free arm of the angle-lever 53 in order to thrustthe pin 38 rearward, during which motion the spring 52 is compressed andthe forward end of the said pinis moved entirely out'of the ath of thewire or freed wholly from the hoo This operation is repeated, as will beunderstood, near the opposite end of the machine. On the return movementof the rack-bar the-shoulder on the right of the actuator 55 moves awayfrom the freearm of the lever 53, so that the spring 52 can return thepin 38 to its primary position and to receivethe free end of a wire tobe bent thereabout. Should the spring fail to wire, which issubsequently ell'ective for effecting the ejectment from the diemechanisms or crimping means of the llnished product. As a matter offact in practice we provide several of these devices, one of them beingshown in detail in Figs. 13 and 14. We will now describe in detail oneof said devices, such description applying to the others, as they arethe same in construction.

Within the bed 2 is inounted a rock-shaft 60, to which are rigidlyunited in some suitable way the hubs of the swinging arms 61. (See Fig.4.) Referring now to Figs. 13 and 14, it will be seen that the upper endof the rock-arm 61 is enlarged to present a head, and in the upper sideof the enlargement is formed a recess 62, which cooperates with a recess63 on the ravity-latch 64, supported by the framewor of-the machine andindependently of the swinging arm 61. The two recesses 62 and 63normally mate, as indi cated in Fig. 13, to form a guide-passage for thewire, and through which said wire is threaded as it is fed toward thehole 29. In the upper side or head portion of the swinging member 61 aconcavity 65 is formed, which normally receives a convex portion 66 onthe under side of the pivoted gravity-latch 64, the relation in questionbeing maintained by the automatic action of the latch. During suchrelation the two recesses 62 and 63 mate to form the passage mentioned.When the recesses do mate, the wire is prevented from lateral movementby the walls of ,the passage formed by such recesses. In other words,the swinging member 61 and cooperating latch 64 act conjointly tomaintain the wire against movement and to also prevent lateral motion ofthe cut blank.

On the upper side of the head portion of the swinging member is locatedan upright projection 66, which fits within a longitudinal slot in thesuperposed latch 64, whereb on the motion of the swinging member reative to the latch the former will be prevented from sidewise action.There is one swinging arm or member 61 and cooperating latch 64 betweeneach pair of die mechanisms, although this is not essential.

The wire is fed toward the bolt 29 and in its passage toward said boltpasses through the passages formed by the complemental recesses 62 and63, and after the shaft 5 is started in action the initial thin thattakes place is the severance of the wire into a blank. Then the ends ofthe blank are shaped to present hooks, following which the die.mechanisms are rendered successively effective to form crimps of thecharacter set forth at predetermined intervals in the blank. The earns25 for effecting the successive action of the blocks or slides 22, whichcarry the upper die members 21, act in succession. The upper (liemembers 2] each includes on its lower edge several salient portions, theintermediate one of which is more prominent than ille side ones, whilethe lower die members are of reverse construction. It will be apparentthat when an upper die member 21 is pressed downward against the wireimposed upon the lower or lixed die member 15 a crimp ol'.thc kind shownin Fig. 17 and also in Fig. H) will be formed. The first (am 25 on theleft initially acts to press the cooperating upper die member downward,following which the remaining earns 25 operate in succession. After theworking portion of a cam 25 passes from out of contact with anantifriction-roller 24 the cooperating die member 21 is returned to itsoriginal position by the force of a spring 23.

To the shaft 60 and at suitable points thereon are rigidly joinedrock-arms, as 70, to the up er ends of which the links 71 are jointed, te 0 posite ends of said links being connected to evers, as 72, fulcrumedon the framework of the machine, and the upper ends of which normallyengage the ineffective or release portions of cams, as 73, splined orotherwise connected to the shaft 5.

The working portions of the two cams 73 are alined longitudinally of themachine and are adapted to enga e the upper ends of the levers'72immediate y after the last slide 22 has been returned to its originalposition and naturally after the formation of the final crimp in the cutlength of wire. When the final crimp is formed, the two cams 73 or theeffective portions thereof simultaneously operate the levers 72, so asto impart a for- 'ward movement to the lower arms of said levers andnaturally a corresponding movement to the arms 70, and hence theswinging members 61. When the working portions of the two cams pass freeof the levers 72, the latter are returned to their original positions bymeans of springs, as 74, connected to the rock-arms 70 and also to theframing of the machine interiorly of the bed 2. On the forward -movementof the swinging members 61 they coact to effect the ejectment of thecrimped stock away from the crimping mechanisms or, as they are in thepresent case, a series of correlated dies. On the action of the levers'7 2 in unison by the cams 73 the swin ing members 61 are moved forward,whic would be toward the left in Fig. '4- and toward the right in Figs.13 and 14. In the last-mentioned figure we have shown the member 61 bydotted lines as being near its extreme forward position, and it might bestated that the forward movement of the said swinging member is anaccelerated one, the working portions of they cams 73 being so shaped asto secure such motion. On the forward motion of the several members 61,which occurs, of course, simultaneously, the latches 64 are caused to beelevated by the riding out of the convex portions or rounded pro'ections66 from the concavities or seats I back of the blank during thehook-forming 6 65 1n the respective swinging members 61, so that thelatches are elevated sufiic1ently to free them from the Wire. I The bacwalls of the recesses 62 then serve to 1mpel the crimped stock forward1n a qulck manner, and, falling from the members 61 said stock dropsinto a cradle, as,7 5, suitably fastened to the forward side of the bed2, and from which the crimped stock can be removed at intervals. On thereturn movement of the swinging member 61 free of the product thelatches 64 drop simultaneously to their original positions, when theseats 65 come opposite the rounded projections 66. I

The latch or controller 64 on the extreme right in Fig. 1 normally engaes under the free ortion of the latch 34, w 'ch latch, as will lieremembered, normally revents motion of the detent 33. When, t erefore,said outermost latch 64 is elevated, it will elevate the latch 34, so asto free the latter from the detent 33, whereby the latter will releasethe extreme forward end of the finished product.

When the detent 33 is rendered ineffective by the elevation of the latch34, said extreme forward end of the product can be readily moved fromout of the notch or recess 27.

- From the outer end of the block 28 there is represented as extending aslotted projection 76, in the slot of which the upper end of therock-lever 31 plays, the outward movement of said lever being controlledby the adjustable stop77, shown as a set-screw tapped through the outerend of said projection 76. Briefly set forth, the operation of themachine constructed as hereinbefore described is as follows: The wire isfed positively into the machine, the leading end thereof throwing theshaft 5 into action, as hereinbefore described. Upon the cutting off ofa predetermined length of wire by the cutting mechanism set in motion bythe shaft the ends of the wire are first bent to form hooks, after whichthe wire is crim ed at predetermined points in itsleng'th. ter the wireis 'crimped it is ejected from the crimping or die mechanisms into asuitable receiver.

We desire to state that we do not limit ourselves to the constructionhereinbefore described, and shown in detail in the accompanyingdrawings, for the construction may be radically modified within thescope of our claims. We have used herein certain terms and desire it tobe distinctly understood that said terms are in their generic senseswith a view of covering equivalent parts.
